CLEANSlNG-TRUNK.

sPEcIFIcA'rIoN forming part of Letters Patent No. 690,652, dated January' 7, l1902. Application inea August so, 1901. seria No. 73,807. (no man.)

To a/ZZ whom, t may concern: f

Be it known that I, FREDERICK H. L. J AMES,

a citizen of the United States, and a resident of awtyrket, in the county of Providence 5 an' State of Rhode Island, have invented a new and useful Improvement in Cleansing- Trunks, (Case 13,) of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, form- Io ing a part of this specification, in explaining its nature.

The invention is in many respects like that described in my application for Letters Patent of the United States (Case A) filed of x5 even date herewith. It varies,v however, from said 'invention in that the rotary valves therein described are provided with an additional function-viz., of feeding the dirt along the escape-passage to its out1et-and` zo thus take the place of the Vmeans for the removal of the dirt therein described-viz., an exhaust-current of air introduced by an exhaust-fan.

The drawing is a View, principally in verti- 2 5 cal central section, of enough of the trunk to illustrate the invention. i

In the drawing, A is a passage through which the cotton or ber is driven or fed by 4 an air-current. B is the grated bottom, the 3o openings in which connect the passage A with the dirt-receiving chambers C. These chambers have outlets cinto the dirt-escapepassage D. The chambers are separated from each other by the partitions c', having the 3 5 curved faces c2 at the outlet. The rotary valve E is mounted in each outlet. It has arms or blades e, which serve to keep the out--` let closed against cross movements or drafts of air between the two passages A and D. As the 4o difference in pressure between the air in they bottom of the passage D, which is'brought close enough to the valves to permit them to vsweep or move over its surface, and thus act to move the dirt onward in the direction 1n which they are moved, each arm of each valve not only acting to thus move onward the dirt delivered by it to the dirt-removal passage, but also the dirtdelivered by as many of the valves as may be beyond it, the dirt being thus by successive impulses of thev various valves transferred gradually to the outlet of the removal-passage.

For rotating the valves I'prefer to use the means described in my said application, and the valve may be continuously or intermittently rotated, as may be preferred.

The trunk may be used in an inclined as y well as in a horizontal position.

Having thus fully described myl invention, Iclaim and desire to secure by Letters Patent of the United Statesl. In a cleansing-trunk, a passage through which cotton or other ber is drawn or im polled, a grated bottom thereto, a passage for the removal of dirt and interposed means for receiving dirt from the cotton and transfers ring it to the dirt-removal passage, which moval passage in close contact with the ldoor thereof and serve to advance the dirt by suc cessive impulses in said removal-passage.

3. In a cleansing-trunk, a passage in which cotton or other ber is drawn or impelled, a grated bottom thereto, a dirt-escape passage and automatic means interposed between the two -passages adapted to feed dirt from one to the other, to form an air-barrier and to au tomatically feed the dirt along the removal= passage.
